Re: MK3 Turbocharger mounted in the rear?
Its not my idea. It is my idea to do it to my supra. It has been done in many V applications to avoid the use of a Y turbo header, because it makes more sense to have the Y in your exhaust with a V application. There are 2 Tiburons and 3 camero here in town with that set up that i know of. They all use meth/water injection and one guy with a camero has lower EGT at 7psi and stock compression than I do with low compression and 10psi w/inter cooler.
Your probably right though, a supra has a good set up.. but i want to upgrade to a turbo with an external waste gate and it seems much cheaper and just as effecient. For a T04 upgrade the traditional way I will have to buy a $700 exhaust manifold. Rear turbo mount style would take a few welds from the MIG to mount my waste gate. However there is no doubt there are more points of failure when it comes to exhaust leaks ect.
Back to me not understanding how hot turbos are. When you are feeding fresh exhaust directly into a turbo your talking serious heat. I've seen vids of people heating a turbo to a glow on an engine dyno. When your feeding your turbine housing exhaust gas that has had time to cool down a bit, the over all performance of your turbo will increase. Not to mention the compressor housing of your turbo is not in the engine bay and is connected to a much cooler turbine housing than a typical set up. Cars have used turbo's for years w/out intercoolers, but this is much different. Consider lower preturbine EGT, meth/water inj, header wrap on everything and you can imagine how people are doing this an still pulling off low outlet EGTs.
Besides you still have all the options of a typical turbo set up when it comes to cooling the boost(intercooler/CO2).
